Machine fault detection using bicoherence spectra


This paper describes the detection and identification of an induction motor's asymmetric faults by measuring vibration data and analyzing the nonlinearity of the machine using higher-order spectral (HOS) analysis. Since damaged or abnormal-state machines often generate highly nonlinear signals, it is desirable to use a tool that can detect and analyze… (More)
